SPECIFICATION forming part of Letters Patent No. 643,389, dated February 13, 1900. Application filed November 20,1899. Serial No. 737,606. (No model.)

To @ZZ whom. it may concern:

Beit known that I, HORACE VYMAN, a citizen/of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to looms, and more particularly to a signal attachment for shuttle-changing looms of the class shown and de scribed in Patent No. 614,369, of November 15, 18%. In said class of looms it becomes necessary for the attendant to visit the loom and place a shuttle with fresh filling on the spare-shuttle holder after the transfer of the spare shuttle to the lay. The spare-shuttle of a pivoted signal-arm upon a stand fixed to l the loom-frame and near the spare-shuttle holder when it is in its inoperative position. "When the spare-shuttle holder moves to transfer the spare shuttle, the signal-arm is also moved to bring the signal into a more prominent position to be seen bythe attendant, who may be at another loom. The display of the signal will notify the attendant that it is necessary to visit the loom to supply another spare shuttle.

My invention consists in certain novel features of construction of my signal attachment, in combination with the spare-shuttle holder, as will loe-hereinafter fully described.

Referring to the drawings, Figure 1 is a plan view of a det-ached portion of one end of the stationary bracket at one end of a loom and the movable spare-shuttle holder-plate of the shuttle-feeder mechanism with a spare shuttle thereon and my signal attachment combined therewith. Fig. 2 is a front view of the parts shown in Fig. 1 looking in the direction of arrow a, same figure. Fig. 3 corresponds to Fig. 2, but shows the spare-shuttle holder-plate of the shuttle-feeder mechanism in its raised position without a spare shuttle thereon (the shuttle having been transferred to the lay) and the signal in its displayed position; and Fig. 4. is a vertical cross-section on line 1 1, Fig. 1, looking in the direction of arrow Z), same figure. The shuttle is shown in broken lines.

In the accompanying drawings, 1 is the upper prtion of the frame at one side of the loom. 2 is the end of the breast-beam- 3 is a stand secured to the frame or loom side. 4 is the spare-shuttle holder-platelet the shuttlefeeder mechanism, bolted to the upper end of the lever or bar 5, pivoted at its lower end (not shown) in the usual Way and as fully shown and described in said Patent No. 614,369. Upon the plate 4 rests the spare shuttle 6, as shown in Figs. 1 and 2.

All of the above parts may be of the ordinary and well-known construction and operation and are fully shown and described in said Patent No. 614,369.

I will now describe my signal attachment combined with the parts shown in the draw-V ings and above described.

An arm 7 has in this instance a weight S thereon at one end and is pivotally mounted on a stud or pin 9, secured t0 the stand 3. The opposite or free end of the arm 7 carries the signal, which in this instance is a flat plate or disk 10, secured to the arm 7 by a screw 11i. The signal-arm 7 isvpivoted to move in a vertical plane and from the horizontal position shown in Fig. 2 to the raised position shown in Fig. 3, and the weight 8 is so arranged relatively to the pivoted end of the arm 7 that it will act to hold the arm in its lowered horizontal position when moved downwardly and also in its elevated position when the projection 7 on the arm 7 is engaged by the upper rear edge 5 of the lever or arm 5 (see Fig. 3) and raised by the .upper and forward movement of the Aspare-shuttle holder-plate 4 to transfer a spare shuttle to the lay.

The advantages of rnyimprovements will be readily appreciated by those skilled in the art. The attendant in tending several looms is often at a distance from some of the looms and cannotsee whether or not there is a spare shuttle on the spare-shuttle holder-plate of the shuttle-feed mechanism of the loom, but

IOO

In a loom of the class described, the co1nbination with the spare-shuttle holder-plate, of a pivoted signal-arm normally held in its loW- ered position, and provided with a weight or its equivalent to hold it in its raised position, 15

substantially as shown and described.
